This is 2007 and quite interesting as someone whose never seen it before

The most interesting points for me;
It wasn't any power spec that Apple drove differentiation on but rather on a new form factor
The perception was that Apple was targeting different users from BlackBerry users, and didn't pose any threat to BlackBerry except from a
brand and
reputation standpoint
I don't think BlackBerry sold its soul, I think it lost it, and is fighting hard to try and get it back
